Now our wavelength is getting longer
because the waves are stretching out.
This make the ________ lower as well
as the pitch we hear.
1. Frequency
2. Loudness
3. Amplitude
Answers
Our wavelength is getting longer because the waves are stretching out.
This make the frequency lower. The correct option is 1.
What is wavelength?The wavelength is the distance between the adjacent trough of the sinusoidal wave.
When the wavelength is increased the waves stretch more. The wavelength is inversely proportional to the frequency
Then, increasing the wavelength will decrease the frequency. The pitch will also gets lower.
Thus the frequency gets lower we hear. The correct option is 1.

Which of the following forces has not changed Earth's surface?
folding
erosion
weathering
gravity
Answers
Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

For a guitar string to produce sound it must _______________.
Answers
Answer: Plucking a loose rubber band will produce a lower sound, while a rubber band that has been stretched tight will make a higher sound. Guitar strings work this way.
Explanation: HOPE THIS HELPS
SRRY IF IT DOESNT
According to the information we can infer that for a guitar string to produce sound, it must vibrate.
What must happen for a guitar string to ring?When a guitar string is plucked or strummed, it creates vibrations. These vibrations travel through the string and cause the surrounding air molecules to vibrate as well.
This vibration of the air molecules produces sound waves, which we perceive as sound. The pitch of the sound is determined by the frequency of the string's vibrations, with higher frequencies producing higher-pitched sounds and lower frequencies producing lower-pitched sounds. In summary, for a guitar string to produce sound, it must vibrate.

What is the difference between friction, conduction, and induction?
Answers
Answer:
Friction, conduction, and induction are all physical phenomena that involve the transfer of energy from one object to another.
Friction is the force that opposes the motion of two objects that are in contact with each other. It is caused by the irregular shape and roughness of the surfaces of the objects, and it results in a loss of energy.
Conduction is the transfer of heat energy through a material from one molecule to another. It occurs when molecules in a material vibrate and collide with one another, and the energy is transferred from the hotter molecules to the cooler ones.
Induction is the process by which an electrical current is generated in a conductor when it is exposed to a changing magnetic field. It is based on the principle of electromagnetic induction, which states that a magnetic field can induce an electric current in a conductor.
Friction is the transfer of heat between two surfaces that are in contact with each other. When you rub your hands together, the friction between them creates heat.
Conduction is the transfer of heat through a material. When you put a metal spoon in a hot cup of tea, the heat from the tea is conducted through the spoon to your hand.
Induction is the transfer of heat through a magnetic field. This is a bit more complex, but it's how things like electric stovetops work.
You will need a magnifying glass and a small piece of scrap paper for this demonstration.
a. Go outside on a sunny day and put the piece of paper on a patch of asphalt, concrete, or a large flat rock. Make sure there is no other combustible material or debris in the vicinity.
b. Hold the magnifying glass so it is close to the paper, with rays of sunlight shining through it. Move the magnifying glass side to side and close or away from the paper until the most concentrated ray of light is shining on the paper. This is the focal point for that magnifying glass.
c. Measure the distance between the focal point and magnifying glass. This is the focal length for that magnifying glass. (Be careful; if you hold the magnifying glass in that place for long enough, the paper will catch fire. Do not ever do this on your skin or clothing, as it can cause serious burns.)

What is the answer to mgh =1/2 mv^2 + 1/5 mv^2 ???
Answers
Answer:
v = sqrt((10/7)gh)
Explanation:
The given equation is:
mgh = (1/2)mv^2 + (1/5)mv^2
To solve for v, we can start by simplifying the right side of the equation:
mgh = (7/10)mv^2
Dividing both sides by (7/10)mv^2, we get:
mgh / (7/10)mv^2 = 1
Multiplying both sides by (10/7)m/gh, we get:
v^2 = (10/7)gh
Taking the square root of both sides, we get:
v = sqrt((10/7)gh)
Therefore, the solution for v in terms of m, g, h is:
v = sqrt((10/7)gh)

why is it difficult for a car to round a curve at high speed
Answers
Answer:
Because the force required to produce this acceleration equals the mass of the car x acceleration, the group of the car is the same but the acceleration is a lot more hence a much bigger force is required. So this is why it's harder for cars to corner at a high speed rather than lower.
Answer:
Vehicles are heavy and have a lot of inertia. This means that if you drive too fast on a curve, your vehicle will keep going straight instead of going around the curve, no matter how hard you drive or slow down to keep it in your lane. Centrifugal force creates a strong outward pull on your vehicle. So all you need to do is slow down before entering a corner. Reducing your speed when you are already on a bend can cause your car to skid.
